I am trying to implement ERPnext for a retail business. Here products have an MRP(Maximum Retail Price) mentioned on them by manufacturer, but a new MRP can be mentioned on the same product whenever the manufacturer decides to increase the product price. In that case, a retailer can have stock of same product with old MRP and new stock with new MRP.
How should I manage this in ERPnext, as there is no option for MRP?
